It is a noble and beautiful spectacle to see man raising himself, so to speak, from nothing by his own exertions; dissipating, by the light of reason, all the thick clouds in which he was by nature enveloped; mounting above himself; soaring in thought even to the celestial regions; like the sun, encompassing with giant strides the vast extent of the universe; and, what is still grander and more wonderful, going back into himself, there to study man and get to know his own nature, his duties and his end. All these miracles we have seen renewed within the last few generations.
